I was having issues with spools falling over while using the split roller type of spool holder that came with my printer, so i made this spool holder which is intended to be screwed to a desk or such.
Might be able to be screwed to a closet wall or such, but i have not tested it, it might break, and there's nothing stopping the spool from falling off if you do this.
The pole is 50mm in diameter, should fit most spools, it's 115mm tall, should be able to handle spools larger than 1kg as well.
The spacing of the filament guide is based on the filament spools i have lying around, with some added clearance, it may not be enough space for all spools, which is why i included longer versions with 30mm and 60mm of additional length.
The author marked this model as their own original creation.
